Abstract
Process for the production of bismuth germanate (BGO monocrystals) with a high scintillation response, based on the growth of a monocrystal from a molten bath in a crucible or container. The container is made from iridium and the melting and growth are carried out under a neutral or weak oxidizing atmosphere. This process makes it possible to produce BGO monocrystals with a high scintillation response, of all random sizes, which are free from light diffusion centers and which can be used as high energy radiation detectors.
